To call the gas emergency line a 3rd time?

[SerenaOverjoyed]

We have savoury-smelling under stairs cupboard that is geuinely stealing my sanity.

In October I got a damp surveyor in who couldn't find evidence of dry rot (phew!) but smelt gas. Gas engineer was called, found a leak and fixed it.

A month or so later we noticed a smell again and called the gas line, but they couldn't find a leak. Since I notice the smell intermittently. We want to sell soon and I'm dreading a structural survey finding something.

Next time I smell it strongly I'll call the gas line. Has anyone called them back to find they were right after all?

Or should I investigate elsewhere?

I have mistaken dead mouse for a gas leak in the past. Even the gas emergency man thought it was gas until him meter told him it wasn't. So any chance it could be that?

Is it near a door or window? I only ask as it was coming from our gas cupboard that's next near the front door so we only smelt it when we had been away a few days. Maybe that's what's happening?

If in doubt call the gas people. Did you see the news from Paris yesterday, 4 people dead in a gas explosion. Get it checked.

We had this problem In our new build house, in the end they shut of the gas as we had a major leak coming from the gas meter oustside which was coming through the kitchen cupboards.
Our gas bill was horrendous but we managed to get that back from the developers.
Do not mess about where gas is concerned we were so lucky.
If you smell gas or even think you do phone them every single time.

I'm thinking you have a dead, uninvited "house guest" laying around. The smell compared to has is very, very similar.

If you are pretty sure you have a gas leak, then obviously you have no choice.
But bear in mind that the pungent chemical deliberately introduced into Natural Gas to make leaks obvious, can cling in damp plaster, damp wood, soil, etc:
The gas itself, which is odourless, has probably long evaporated.

Thanks all. Smelt clear this morning but it tends to be at night. Will call gas line if I smell it tonight.

OnlyaMan this is possible. It may have been leaking for months, we only triggered it as a gas smell and not a damp smell when the surveyor noticed it. Any idea how we might fix this.

I was wondering if it might be drains? Or sewer gas? I'm calling a plumber..

Would love it to be a dead rodent, but the smell wouldn't linger on/off right?
